  FIG. 1 is a diagram schematically illustrating the principle of transmitting or transmitting transmission data such as character data by wireless communication using a portable data transmission / reception terminal device according to an embodiment of the present invention. For example, when a portable data transmission / reception terminal device (abbreviated as “terminal” or “transmission / reception terminal” in the figure and the following description) A transmits transmission data by radio waves, it exists in an area where the radio waves can be received. The other terminals B, C, and D that receive it receive the transmission data. At this time, the radio wave transmitted by the terminal A is preferably a weak radio wave that does not require a license based on the Radio Wave Handling Law. The other terminals B, C, and D transfer the received data if the received data does not belong to their own destination, and if it corresponds to the indirect mail described later. In addition, even if the mail is intended to be transferred to an unspecified number of people, for example, information such as an advertisement described later, it is not a direct mail or an indirect mail, other terminals E and F existing in the area , G.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, in order to simplify the description, transmission / reception data will be described assuming an e-mail or an e-mail for an unspecified person. The mail for unspecified people is, for example, a message that does not have any trouble such as news, advertisements, bargain information, or a message that can be read by an unspecified number of people. Specifically, the following three types of transmission / reception data can be considered.
(1) When direct mail is sent Terminal A designates a destination and directly sends it to a specific terminal (for example, D). The transmission data is continuously stored only in the terminal D in which the destination information of the electronic mail and the user identification information of the transmission / reception terminal are in a predetermined relationship (for example, match), and only the user can view the mail. However, if there is no specific terminal (for example, G) as the destination in the communicable area, the e-mail may not arrive, but both the transmitting side (A) and the receiving side (G) can communicate. Emails will be forwarded when you get close to the area.
(2) Indirect mail is a case where the terminal A designates a destination and transmits it to a specific terminal (G), and one or more other terminals existing between the sender and the receiver Performs relay communication (or mail transfer) regardless of. In the embodiment described later, when the relaying terminal (D) stores the user identification information of the destination terminal (G) in the address book, the data received by the terminal D is temporarily stored, When the mobile terminal approaches the terminal G and comes within the communicable area, the mail from the terminal A is transferred to the terminal G. Note that a plurality of unspecified terminals B, C and E, F may relay to the specific terminal G by relaying one after another. In this case, the terminals B, C, and D to be relayed are set programmatically so that only the mail having the destination information as itself can be read so that the contents of the message cannot be seen. Even if there is no destination terminal device in the communicable area due to the presence of the terminals B to F as relays, the e-mail is delivered to a specific terminal G farther away by being transferred one after another.
(3) When forwarding mail that is not actively selected by the user, such as news and advertisements, etc. When sending to an unspecified number of terminal devices without specifying a destination, all terminals in the communicable area And can be received by all terminals, and the contents of the received data can be read. The transmission / reception data is not limited to character data (or character code), but may be graphics or symbols, or photographed image data. In the following description, data to be transmitted and received is generically called mail or the like.

And a battery 274. The communication unit includes a transmitter and a receiver that transmit and receive weak radio waves that do not require a license according to the Radio Control Law. The communication unit modulates code such as character data, data such as characters and symbols, or dot data and transmits and receives them. The CPU 262 performs the transmission / reception operation of the communication unit 261 and the writing / reading control of the work RAM 264 and the S-RAM 267 based on the program data of the built-in ROM 263, and also transmits data between the CPU 35 of the data display / creation device 30. Give and receive. The CPU 262 and the ROM 226 are electrically connected to the connector 36 of the data display / creation apparatus 30 via a memory bank controller (hereinafter abbreviated as “MBC”) 271 and a connector 237. A reset IC 265 is connected to the CPU 262. The MBC 271 switches which of the ROM 266, the S-RAM 276, and the CPU 262 is connected to the address bus of the CPU 35 as viewed from the CPU 35 based on the specific address data of the address bus accessible from the CPU 35. The MBC 271 has a built-in timer that measures the date and time as necessary, and is used as a time data generation source when it is necessary to add the time data during communication to the transmission data and transmit it.

  The ROM 263 stores in advance a communication program (a program for realizing functions of flowcharts shown in FIGS. 10 to 13 described later) when the cartridge 20 is used alone as a transmission / reception terminal, and is executed by the CPU 262. The ROM 266 stores a program for displaying received data and / or creating transmission data (the flowcharts shown in FIGS. 14 and 15 described later) executed by the CPU 35 when the cartridge 20 is mounted on the data display / creation device 30. Program for realizing the above function) is stored in advance.

In FIG. 6, the data display / creation device 30 includes a CPU 35, and the CPU is connected to the connector 273 of the cartridge 20 via the connector 36. In addition, a liquid crystal display 32 and an operation switch 33 are connected to the CPU 35.

  FIG. 7 is a diagram schematically showing the storage area of the S-RAM 267. In the figure, the S-RAM 267 includes a reception data storage area 267a, a transmission data storage area 267b, an address book storage area 267c, and a user identification information (ID information) storage area 267d. The received data storage area 267a is an area for storing data such as mail received from other terminals. The transmission data storage area 267b is an area for storing transmission data input by the user by operating the operation switch 33 when used by being attached to the data display / creation device 30. In the reception data storage area 267a and the transmission data storage area 267b, not only the mail data to be transmitted (transmission data body) but also various data added to the mail data (for example, the signal type, self shown in FIG. 9). ID, terminal ID, transmission data, checksum, timing information, received flag, etc.) are also stored. The received flag is a flag indicating that the same mail has been received by the direct mail transfer method. The user ID information is information for specifying a transmission / reception terminal device, and is, for example, a name, an address, a date of birth, a telephone number, or the like, but may be a character or numeric string that can be distinguished from other terminals. The address book data storage area 267c stores user ID information of other terminals that are a plurality of counterparts that the user wishes to communicate with. This is used as ID information for determining whether to relay mail when transferring mail by the indirect mail transfer method. For example, one or more user ID information unique to a friend's terminal is preset and registered in the address book data storage area 267c, and when a mail with destination information addressed to a friend is received, the cartridge 10 It will work as a repeater that relays mail transfer.

  Referring to FIG. 5 again, power supply switching circuit 268 supplies power to battery 269 when cartridge 10 is mounted on data display / creation device 30 and power is supplied from data display / creation device 30. When power is not supplied from the data display / creation device 30, the power of the battery 269 is supplied to the S-RAM 267 to prevent the data stored in the S-RAM 267 from volatilizing.

In FIG. 6, the data display / creation apparatus 30 includes a display device 31, an input device 32, a CPU 35, and a connector 36 for connecting to the transmission / reception terminal device 20.

  FIG. 8 is a diagram showing an outline of a data transmission / reception procedure. FIG. 9 is a diagram showing a format of communication data. Next, a data transmission / reception procedure will be described with reference to FIGS. First, the transmitting / receiving terminal device 1 transmits a preamble signal prior to data transmission. As shown in FIG. 9, the preamble signal includes a signal type, a self ID, transmission data information, and a checksum unit. The signal type is data for distinguishing a preamble signal, a response signal, and a data body signal. The self ID is user ID information of the transmitting / receiving terminal device 1. The transmission data information includes the creation date and time of the e-mail to be sent, the user ID information of the creator, the destination user ID information, the data type for identifying e-mail or news, direct e-mail or indirect e-mail in the case of e-mail Including the mode type and expiration date data. The expiration date data is information for deleting the data from the SRAM 267 when the sale period or the event period has passed, for example, when the transmission / reception data is news data such as supermarket sale information or event information. The checksum part is used to check whether correct data has been received.

  When the transmission / reception terminal device 2 on the receiving side receives the preamble signal, determines whether or not it is an e-mail to be received based on transmission data information included in the preamble signal, and is an e-mail to be received A response signal is transmitted. Similar to the preamble signal, the response signal includes a signal type, a self ID, transmission data information, and a checksum part. In addition to these, user ID information (user ID information included in the preamble signal) and timing information of the transmitting / receiving terminal device 1 are included. The timing information is used to match the transmission timing of the transmission / reception terminal device 1 with the reception timing of the reception side transmission / reception terminal device 2, and is specifically information indicating how many seconds after the response signal is transmitted.

  The transmitting side transmission / reception terminal device 1 waits for the response signal to be transmitted from the receiving side transmission / reception terminal device 2 after transmitting the preamble signal, but when receiving the response signal, in accordance with the timing information included in the response signal, The data body signal is transmitted, and the transmission / reception terminal device 2 on the reception side receives the signal.

  FIG. 10 is a flowchart of the main routine of the communication program. 11 and 12 are flowcharts of a transmission subroutine and a reception subroutine in the main routine flowchart. FIG. 13 is a flowchart showing details of the determination process (step 124) as to whether or not to receive in the reception subroutine.

  Next, with reference to FIGS. 10 to 13, the operation during communication of this embodiment will be described. When the battery 274 is attached to the transmission / reception terminal device 20, the CPU 262 executes a communication program stored in the ROM 263. First, in step 10, it is determined whether or not user ID information is input. If not, step 10 is repeated to wait for input of user ID information. That is, the transmission / reception terminal device 20 does not perform communication unless user ID information is input. Here, the user attaches the transmission / reception terminal device 20 to the data display / creation device 30 and inputs user ID information using the display device 31 and the input key 32. When the user ID information is input, the process proceeds to step 11 and thereafter steps 11 to 15 are repeated. Specifically, in step 11, a transmission subroutine shown in FIG. 11 described later is executed. Subsequently, at step 12, a reception subroutine shown in FIG. In step 14, the e-mail stored in the SRAM 267 and the like that have expired are deleted. In step 15, a time waiting process is performed. This is to increase the duration of the battery 274 by taking a transmission / reception interval to suppress current consumption.

  The transmission / reception terminal device 20 repeats step 11 to step 15 until the battery 274 is exhausted. However, when the display / creation device is mounted, the CPU 262 is in an inoperative state, and the data display / creation program shown in FIG. When the display / creation device is removed again, the CPU 262 operates, and after step 10, the operations of step 11 to step 15 are repeated.

  Details of the transmission subroutine will be described with reference to FIG. In the transmission subroutine, data received from other transmission / reception terminal devices and stored in the reception data area 201 in the SRAM 267, or self-transmission data in the SRAM 267 created in the display / creation program new creation subroutine shown in FIG. Data stored in area 202 is transmitted. First, in step 111, it is determined whether there is data to be transmitted, that is, in the received data area 201 (excluding the e-mail addressed to itself) and the self-transmitted data area 202 (excluding the received direct mail) in the SRAM 267. It is determined whether there is an e-mail or the like. If there is no data to be transmitted, the transmission subroutine is terminated and the process returns to the main routine. If there is data to be transmitted, the process proceeds to step 112, and a preamble signal is transmitted. In step 113, the process waits for reception of a response signal, and proceeds to step 114 after reception. In step 114, it is determined whether or not the received signal is a response signal based on the signal type included in the received signal, and a sum check is performed to determine whether or not the received signal is correct. If the received signal is not a response signal or a correct signal, the process proceeds to step 119. If it is a response signal and is a correct signal, the process proceeds to step 115, and it is determined whether or not it is a response to its own preamble signal based on the transmission / reception terminal device 1ID and transmission data information included in the response signal. If it is not a response to its own preamble signal, the process proceeds to step 119. If it is a response to the own preamble signal, in step 116, data is transmitted at a transmission timing based on the timing information included in the response signal. In step 117, it is determined whether or not the transmitted data is a direct mail. In the case of direct mail, in step 118, the received flag of the self-sending data area 202 in the SRAM 267 is set. If it is not direct mail, the process proceeds to step 119. In step 119, it is determined whether there is other data to be transmitted. If there is another data, the process returns to step 112. If not, the transmission subroutine is terminated and the process returns to the main.

  Details of the reception subroutine will be described with reference to FIGS. In the reception subroutine, in step 121, it is determined whether or not a write area remains in the reception data area 201 in the SRAM 267. If not, the reception subroutine is terminated and the process returns to the main routine. If it remains, reception is performed in step 122. If there is no reception, the reception subroutine is terminated and the process returns to the main routine. If received, it is determined in step 123 whether or not the received signal is a preamble signal, and a sum check is performed to determine whether or not the received signal is correct. If the received signal is not a preamble signal or a correct signal, the reception subroutine is terminated and the process returns to the main routine. If it is a preamble signal and is a correct signal, it is determined in step 124 whether or not data as shown in detail in FIG. If the data is not to be received, the reception subroutine is terminated and the process returns to the main routine. If it is the data to be received, a response signal is transmitted in step 125, and in subsequent step 126, it is received at a timing based on the timing information included in the response signal. In step 127, it is determined whether or not the received signal is a data body signal, and a sum check is performed to determine whether or not the received signal is correct. If the received signal is not a data body signal or a correct signal, the reception subroutine is terminated and the process returns to the main routine. If it is a data main body signal and is a correct signal, the process proceeds to step 128 where the data is stored in the reception data area 201 in the SRAM 267, the reception subroutine is terminated, and the process returns to the main routine.

  With reference to FIG. 13, the determination of whether or not to receive in step 124 of the reception subroutine will be described in detail. First, in step 1241, it is determined whether the data to be transmitted is news based on the transmission data information included in the preamble signal. If it is news, the process proceeds to step 1247. If it is not news, the process proceeds to step 1242 where it is determined whether or not it is direct mail. If it is a direct mail, it is determined in step 1243 whether or not the address is me. If it is me, the process proceeds to step 1247. If not, it is determined that the data is not to be received. If it is determined in step 1242 that the mail is not a direct mail, it is determined in step 1244 whether the mail is an indirect mail, and if it is not an indirect mail, it is determined that the data is not to be received. If it is an indirect mail, it is determined in step 1245 whether or not the address is itself. If not, the process proceeds to step 1246, and it is determined whether or not the destination is included in the address book data. If it is listed in the address book data, the process proceeds to step 1247. If it is not listed in the address book data, it is determined that the data is not to be received. In step 1247, it is determined whether or not there is the same data in reception data area 201 or self-transmission data area 202 in SRAM 267. Specifically, it is determined by comparing transmission data information included in the preamble signal with transmission data information of data stored in the SRAM 267. If it is determined in step 1247 that the data is not the same, it is determined that the data is to be received. If it is determined that the data is the same, it is determined that the data is not to be received.

  FIG. 14 is a flowchart of the main routine of the display / creation program. FIG. 15 is a flowchart of a new transmission subroutine in the flowchart of the main routine. FIG. 16 to FIG. 18 are examples of the execution screen of this program. Next, with reference to FIGS. 14 to 18, the operation at the time of data display / creation of this embodiment will be described.

  When the data display / creation device 30 is attached to the transmission / reception terminal device 20, the CPU 262 enters an inoperative state, and the CPU 35 executes a display / creation program shown in FIGS. 14 and 15 (to be described later) stored in the ROM 266. FIG. 16 is an example of a screen that is initially displayed when the data display / creation apparatus is mounted. Here, a list of received data is displayed. In FIG. 16, the selection cursor 44 is moved by the input of the input key 32a in the vertical direction. When the data does not fit within one screen, the list display 40 scrolls when the cursor 44 goes to the upper and lower ends. Any one of the content display button 41, the new transmission button 42, and the self-sending mail display button 43 is selected (black / white reverse display), and the selection can be changed by the left / right input of the input key 32a. By selecting these buttons and pressing the input key 32b, a content display screen as shown in FIG. 17, a new transmission screen as shown in FIG. 18, and a self-sent mail display screen are displayed. The self-sending mail display screen is substantially the same as that shown in FIG.

  In the display / creation program, first, in step 131, it is determined whether or not user ID information has been input. If it has not been input, input of user ID information is requested in step 132. If it has already been entered, the process proceeds to step 133. In step 133, a received data list display screen as shown in FIG. 16 is displayed. If it is determined on this screen that the content display button 41 has been pressed in step 134, a content display screen as shown in FIG. 17 is displayed in step 135. If it is determined in step 136 that the new transmission button 42 has been pressed, a new transmission subroutine shown in FIG. 15 described later is executed in step 137. If it is determined in step 138 that the self-sending mail display button 43 has been pressed, a self-sending mail display screen substantially similar to that shown in FIG. 16 is displayed in step 139.

  The content display screen will be described with reference to FIG. On the content display screen, the content of the data designated by the selection cursor 44 on the list display screen is displayed. The content of the data is displayed in the content display area 50. When the data does not fit in one screen, the content display area 50 is scrolled by the input of the input key 32a in the vertical direction. Any one of the “Reply to this mail” button, the “Forward this mail” button, and the “Return to received mail list” button is selected, and the selection can be changed by the left and right input of the input key 32a. Each process is performed by selecting these buttons and pressing the input key 32b.

  The new transmission subroutine will be described with reference to FIGS. 15 and 18. In the new transmission subroutine, an e-mail or the like to be newly transmitted is created. FIG. 18 is an example of a display screen. In FIG. 18, the new transmission screen is divided into upper and lower parts, and the upper half is a creation area 60 in which an e-mail or the like being created is displayed. In the lower half, a so-called software keyboard 61 is displayed. Each key in the software keyboard 61 is selected by the input key 32a. The selected key is displayed in black and white inversion. By pressing the input key 32b, a character corresponding to the selected key is displayed at the cursor position in the creation area 60. By repeating this operation, an electronic mail or the like is created. When the creation of the e-mail or the like is completed, the send button 62 is selected by the input key 32a and the input key 32b is pressed. Then, input of the destination, data type, mode type, and expiration date is requested, and the transmission date information is created by adding the creation date and time and creator user ID information to these input data. The data body and transmission data information are stored in the self-transmission data area 202 in the SRAM 267. The stored data is automatically transmitted in the transmission subroutine of the communication program after the data display / creation device 30 is removed.

  In the new creation subroutine, first, in step 140, it is determined whether or not a write area remains in the self-transmission data area 202 in the SRAM 267. If not, the new transmission subroutine is terminated and the process returns to the main routine. If it remains, in step 141, new transmission data is created by the software keyboard as described above. When the creation is completed, input of transmission data information (destination, data type, mode type, expiration date) is requested in step 142. In the following step 143, the creation date and creator ID information are added to the transmission data information. In step 144, the data body and the transmission data information are stored in the self-transmission data area 202 in the SRAM 267, the new creation subroutine is terminated, and the process returns to the main routine.

  The transmission / reception data can be transmitted / received in the same manner as well as image data, audio data, game data, etc. as well as electronic mail or news. In this case, it is only necessary to distinguish not only e-mail and news according to the data type of the transmission data information but also other data as described above. The game data can be, for example, character data or item data that is not stored in advance in a game program ROM (including a semiconductor ROM and a CD-ROM). In addition, data can be spread over a wider range by deleting a reception function of the transmission / reception terminal apparatus 20 and attaching a terminal apparatus having only a transmission function to, for example, a Takkyubin truck.

  FIG. 19 is an image diagram of a fixed data creation / transmission apparatus according to another embodiment of the present invention. In the embodiment described above, data created by connecting the data display / creation device 30 is transmitted / received between the transmission / reception terminal devices 20. On the other hand, the fixed-type data creation / transmission apparatus of this embodiment can create more complicated data and transmits the created data. The transmitted / received terminal apparatus A receives the transmitted data, and the transmitted / received terminal apparatus A further transmits to the transmitted / received terminal apparatus B.

  FIG. 20 is an external view and a block diagram of the fixed data creation / transmission apparatus. In FIG. 20, the fixed data creation / transmission device 70 includes a display device 71, a personal computer 72, a communication unit 76, and an input device. The input device includes a keyboard 73, a scanner 74, and a microphone 75. Further, a digital camera or the like may be used. By preparing various input devices, complex data can be created. The personal computer 72 includes a hard disk 721. A data creation program and a data transmission program are stored in advance in the hard disk, and the created data is further stored. Since the data creation program and the data transmission program are substantially the same as those in the above-described embodiments, their descriptions are omitted. Data is created using the keyboard 73, scanner 74, microphone 75, etc., and stored in the hard disk 721. Then, the data of the hard disk 721 is read and transmitted through the communication unit 76.
